@Bridkarl, you will get this to go. In terms of the "correctness" of having modified the circuit, this may have occurred during WWII when new radios and even replacement tubes were not available (although this radio should have been rather new). For the lack of being able to get an 84, replacing the transformer, so the tech could use a 5Y3 may have been a bit extreme but, hey, you do what you can do. Bottom line here, if you look at the 41-250 schematic, duplicate that exactly, except hook up what ordinarily went to Pin 4 of the 84 to pin 8 of the 5Y3, you should be good.
